memesbest mode in which I have contemplated applying that principle, soas to distinguish it I from other inventions.

The present improvements, relating as indicated, to the manufacture ofmatrices for typographs,involve the provision of a driving press orpunching mechanism of special design adapted for such manufacture. Thispress mechanism includes a number of importantfeatures of construction,it being understood, of course, that such press mechanism is notnecessarily limited in its application to this particular field of use,although designed especially fo'rthe purpose of punching or strikingcharacter impressions in matrix bars, suchas are used in typographmachines.

The object of the invention is to provide means for the rapid andeconomical manufacture of such matrix bars, and at the same time toproduce bars having their matrices as nearly perfect as possible, bothin their outline, depth of strike and uniformity of alinement. To theaccomplishment of the foregoing and related ends, the invention thenconsists of the mechanism hereinafter above indicated, for themanufacture of matrices; Fig.2 is a plan view of the lower portion, orbed, of such machine, which'includes a chuck for holding the matrix barswhile being punched, along with various accessory mechanisms, as will belater set forth, the plane of the view being indicated by the line 2--2,Fig. 1, looking down- Specificationof Letters Patent.

In its general form, my improved matrix driving press or punchingmechanism resembles an ordinary hydraulic press. Thus the bed 1 of themachine, which will be more particularly described later, is supportedon a table-like top 2, carried by a vertically reciprocable piston 3mounted in a cylinder :4; that rests on the base 5 of the machine.

Inasmuch as the range of movement required for the operation of punchingmatrices is very short, removable blocks 6 are I 'matter of detaileddescription, to the chuck for holding the matrix-bars while they arebeing punched, such chuck, along with the supporting bed 1 andappurtenant parts, being shown in plan view in Figs. 2 and 3. One jaw ofthe chuck is in effect a rectanguvlar recess 10 formed in the solid bodyof the bed itself, at the end of a longitudinal slot 11 whichconstitutes a slide-way for the other or movable jaw 12. To therectangularly related faces of such fixed chuck jaw are fitted hardenedsteel plates 13 and 14:, respectively, both of substantial character,

while the inner end of the movable jaw 12 similarly carries ahardenedsteel block 15, so. as to withstand wear and insure absolutely accurateresults. The block thus carried by the movable jaw, is detachablysecured thereto by a screw-fastening 16, so as to be interchangeablewith other similar blocks that differ from each other merely in theirthickness, the object being to provide a recess 17 between such blockand the plate 14 which forms the opposite face of the fixedchuck jaw,that will have substantially thedimensions of .the blank matrix A inwhich it is desired to form the character impression.

. The direction of movement of the chuck jaw 12, it will'be observed, isalong a straight line thatdivides the angle between the two blankmatrix-bar in rectangularly related directions; that is, it will pressit fiat-wise against the one plate 14 of the fixed jaw, and end-wiseagainst the other such plate 13. The dimensions of the recess 17areprefer- 1 on which the jaw extends.

.metal in the first-named direction when the punch is driven, the flowbeing confined to a lateral direction, although, of course, very slight,owing to the pressure of the jaws against the flat sides. The lattersides, however, can be trimmed or ground plain, much more readily thancan the edges,and with much less likelihood of throwing the characterstruck in thematrix bar out of line.

Themovable jaw 12 is normally held in retracted position by a heavycompression spring 20 in a recess 21 in the bedl, said spring engagingwith its outer end a pin 22 depending from such jaw, (see Figs. 2, 3 and5). A set-screw 24L threadedin an adjacent portion of the bed 1 near therear end of the jaw, is adapted to engage a shoulder 25 on the latterand thus form an adjustable stoppreventing the retraction of the jawmore than a predetermined amount. Such amount is gaged to leave a spacebetween the forward end of the j aw and the juxtaposed plate of thefixed jaw just sufficient to permit of a blank matrix A being slidtherealong by the feeding mechanism to which attention will be directedlater.

Actuation of the movable jaw 12 inwardly against said spring 20 issecured by means of a piston 26 mounted in a hydraulic cylinder 27 thatis secured to the face of the bed By admitting water under pressure tothis cylinder, the piston is forced inwardly, imparting a correspondingmovement to the jaw 12 which may be held under any desired pressureagainst the fixed jaw 10, as will be obvious.

The blank matrices A, the general form of which in the present instanceis indicated in the sectional views of the vmechanism,

Figs. 6, 7 and 10, as well as in the detached views of Figs. 17 andlS,are designed to be heldin a trough-like magazine 30 that is adapted tobe removably secured in a suitable recess 31 extending at right anglesto the face of the fixedjaw 10, onto which is fitted the plate 14:, thelatter having an openin g 'alin-ed with the inner end of the troughmatrices forward to thus eject them succes-.

sively into the space in question. The magazine is locked in the recessprovided therefor in the bed by means of a pivotal latch 34, shown inelevation in Fig. 16. By turning such latch into the position shown indotted outline, the trough may be withdrawn, and

therein, the plunger 32' being first drawn back by means of a handle"35', as will be readily understood.

In 'or'der'to transfer or feed the successive matrices, as they aredischarged into the space between the movable'jaw 12 and the opposedface of the fixed jaw 10, plunger 40 is mounted in-the bed 1 of themachine so as to be reciprocable at right angles to the magazine 30, orin other WOI'dSIlIlZL direction parallel with such face, such-plungerbeing provided at its inner end with an arm 41 that carries a plate-likefinger 42 adapted in one position of the plunger to entirely clear suchtrough, as shown in Fig. 7, but capable of moving across the end ofthetrough into the position shown in Fig. -8. The effect of such movement,provided a blank matrix A has been ejected in front of the finger, willobviously be to transfer the latter into position'in front of the block15"carried by the movable jaw 12; in other words, will leave such blankmatrix in place to be pressed or clamped, as previously described,between the two jaws-of the chuck when the movable jaw is closed on thefixed jaw. In order to permit such movement of the finger, the face ofthe movable 'jaw'is transversely recessed as shown at 43 in Fig. 14; j

The finger 42, it wi'll'be observed, extends in both directions from thearm 41,the longer extension being adapted to obstruct the end of thetrough 3O inthe position of said finger illustrated in Fig. 8, thuspreventing the ejection of a freshmatrix blank until the operator isready. The shorter extension of such finger, moreover, is likewiseadapted to remain in front of the trough and similarly prevent theejection of a fresh blank 1 in the intermediate position of such fingershown 111 Fig. 9.

Plunger is normally actuated inwardly by .a compression spring, 44, [butmay be moved outwardly by means of a knob 45 on its outer end, eitherthe full distance shown in full lines in Fig. 2, or simply far enough toallow a pin 46 thereon to escape from a slot 47 in a tubular bearing 48,which also serves to hold the compression spring in place, so that byturning the plunger a trifle it will beheld in the'position shown infull lines in Fig. 3 Such last-named position corresponds with theposition in which the forward extension of the finger 42 'blocks thetrough '30, while the'fully withdrawn position of the plungercorresponds with the position of the finger illustrated in Fig. 8, inwhich a matrix has been moved intooper- ,ative position inthe' chuck,while the longer extension of the finger blocks the trough.

In other words, the trough is only entirely 1 is left between the block15 on the movable jaw of the chuck, and'the plate 14 of the fixed jaw,consists of a hardened steel plate .50 carried on the upper face ofasubstantial slide 51 that is reciprocable by means of a bell-crank lever52'on the front face of the bed, as shown in Figs. 1, 2 and 3. Thereason for the use of a hardened steel plate in this connectiomand forthe heavy character of the slide, is that the full force of the verticalcompression stroke of the hydraulic plunger is, of course, taken by suchplate.

shown in Figs. 10 and 11, in which a matrix bar, positioned in the chuckas has just been described, is supported atthe proper elevation to beengaged by the punch when the bed 1 of the machine is raised. 1 Uponcompletion of the strike and the retraction of the movable chuck jaw 12,the slide 51 is also withdrawn, thus allowing the punched matrix to dropinto the recess 53 in front of such slide, as shown in Fig. 12. Uponagain moving the slide inwardly into its normal position, such matrix isshoved into the upper end of a passage 54, and discharged through thebottom of the bed.

'Tl'i e general form of the punch B employed in driving characterimpressions into the blank matrix bars' is well indicated in Figs. 7, 10and'19, from which it will be noted that the lower end 7) of the punchis formed to enter the recess a in the opposed edge of the matrix bar,such recess being a characteristic feature of the particular bars inhand and it being understood that the face ofthe punch may bechanged inform to suit the kind of matrix bar in hand. I

have found where a character impression is thus formed by means ofapunch lnstead-of to have a perfectly plane printingface. It

does not suffice to have the punch face perfectly plane, for I havefound that the finer the line beingstruck, the deeper the impressionremains, whereas a relatively wide face on the punch, although impressedto the same depth .in the material, will leave a relatively shallowerstrike. Accordingly, in forming the punch face of a character such, forexample, as a capital C (see Fig. 19), I lap off the narrower portionsof such character, as indicated in asomewhat exaggerated fashioninthe'figure in question. When such a die is impressed into the materialof the blank, while the lapped-off portions do not penetrate as deeplyas the broader portion, the result willbe an intaglio impression hav-"its bottom in substantially the same plane.

There will, of course, be a different unch for each character, andthebody 0 such punch will correspond in its cross-sectional dimensions withthose of the matrix, being just atrifle less, sothat the punch may movefreely in the well or recess in the bottom of which the matrix blank isheld gripped between the chuck j aws. As a matter of fact, as explainedbefore, it is the bed 1 of the machine, with such chuck jaws and matrixblank, that. are moved relatively to the punch, rather than vice versa,the range of movement being slight, since-it is only necessary to lowerthe blank sufliciently to allow the punch to clear the recess a in suchblank, and thus permit of the insertion of a second blank after thecharacter impression has been struck in the first 1 The upward movementof the bed of the machine carryingthe blank, is limited by theengagement of the flat upper faces of the chuck jaws with a plate 60secured to the under side of the head 7, and formingpart of the meanswhereby the punch is secured to such head.

In order to adjust the depth of the strike, since the bed and the headthus occupy a fixed relation at the end of the punching stroke of thepress, it is necessary to provide for the vertical adjustment of thepunch. The plate 60, just referred to, is accordingly slidably heldinways 61 in a second plate 62 directly attached to the under-side of thehead, said ways inclining slightly to the horizontal, as indicated inFigs. 7 8 and 9. The first-named plate 60 is provided with an under-cutslot 63 adapted to receive and slidably hold block 64 of T-shape, to

which in turn is attached the punch B by punch and its supporting blockbeing held againstsuch movement by reason of. the .en-

. gagement of the former in the well. 17 between the chuck jaws, suchpunch will be slightly raised or lowered, depending upon the directionof movement of said plate 60. Such movement'is effected by means of athreaded spindle 66. rotatably but longitudinally immovably held in abracket 67 attached to the front face of the head 7 The outer end ofsuchspindle is provided with a hand-wheel 68 to facilitate its rotation,while the threaded portion thereof engages with an upwardly projectingarm 69 on the plate. By means .of such screw and the slight angle of theways, it will obviously be possible to secure a very fine adjustment ofthe punch vertically in the well, and thus obtain a strike of. exactlythe depth desired in the production of any given character impression;By providing a micrometer scale (not shown); in connection with thewheel 68, or other movable part associated with the adjustment of thepunch, the correct position of parts for any particular punch, onceascertained, can bereadily returned to when the punch is used again,

such correct position being empirically determined 1n the firstlnstance. In other words, the character impression is struck in theblankmatrix, and the depthof such immatrices wlth my present improvedmecha-' nism, is the distance between the bottom of such impression andthe back of the bar. In other words, Iv have found that it is much moreadvantageous to measure the drive from the back of the bar instead offrom its face. This distance a" (Fig. 20) being preserved accurately,the distance a between the front and back faces of the matrix bars mayin turn be measured with referenceto I the same backs, and thus thedepth of the impressions below the plane of such faces be likewiseaccurately determined. method of gaging the, location or depth of thecharacter impressions in matrices of the kind in hand, has, soffar as Iam aware never been attempted before.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the steps ormechanism herein disclosed, provided the means stated by any .of thefollowingclaims or the equivalent of such stated means be employed.
